Can Nanotech Make A Comeback For Investors? (ALTI, IBM, TINY, NSPH, PXN)

How long has it been since nanotechnology was on the tip of everyone’s tongue as the next great speculative investment frontier?  It seems like ancient history.  But we have seen news from Altair Nanotechnologies Inc. (NASDAQ: ALTI), IBM (NYSE: IBM), Harris & Harris Company, Inc. (NASDAQ: TINY), and Nanosphere, Inc. (NASDAQ: NSPH) this week.  We have even seen a bit of a move in the PowerShares Lux Nanotech (NYSE: PXN) ETF that tracks nanotech this week.

This week was actually more nanotech-related news than we have for some time even if there is still no clear direction on which way the political environment will treat nanotech in the months and years ahead.

Is Nanotechnology the Next Asbestos? (PXN)

Nanotechnology is one of those industries that has advocates lining up for it and against it.  The theoretical possibilities are endless.  These could be in micro-computing, arterial plaque attacks, tissue repair, cleaning surfaces, cancer fighting, and on and on and on.

But nanotechnology also has many critics, particularly those who are concerned that nano-bots or nano particles could be used against people.  In a report published in advance from NATURE NANOTECHNOLOGY, the new fear is that nanotechnology’s carbon nanotubes injected into mice showed similarities to asbestos.

The pilot study in a small number of mice shows that long multiwalled carbon nanotubes introduced into the abdominal cavity can cause asbestos-like pathogenic behavior. The results suggest the need for further research and caution before introducing nanotube products into the market.

Mesothelioma is a death sentence.  If nanotech generates even the same fears, this technology may be crushed before even the simple applications can get off the ground  It sounds like they need a nano-drug now, one to fight nanothelioma.

The nanotech ETF, the PowerShares Lux Nanotech (AMEX: PXN) was down 2% at $14.51, although it was on thin volume when the market itself was soft.
